FIGURE 4 is Aan exploded view showing the major components of the doublewindow construction in cross section;

FIGURE 5 is a fragmentary sectional view, similar to FIGURE l, showing amodification wherein the Window `is arranged as a triple windowconstruction;

FIGURE 6 is another fragmentary sectional View, showing a furthermodification wherein the window is arranged as a quadruple windowconstruction.

Reference is rst directed to FIGURES 1 through 4. The double windowconstruction here illustrated is formed almost entirely from a pluralityof extruded metal parts which are separated from each other by yieldablesealing and cushioning means, which are also extrusions, in this caseformed Iof rubber or other elastomer.

The double window construction includes an outer mounting frame member 1which is formed in-to a rectangular outer frame structure. The mountingframe member 1 includes a transverse web 2 provided along itsWeatherside margin, or left side margin as viewed in the drawings, withan internally directed weatherside flange 3. The flange 3 terminates inan inturned lip 4 and is pro- `vided along its inner wal-l, confrontingthe inturned lip, `with a retainer bracket 5 of angular cross section.

The inturned lip 4 and retainer bracket 5 receive a 3,203,653 PatentedAug. 31, 1965 ICS sealing mem-ber 6, yformed of rubber or otherelastomer, and having a V-shaped end 7 which fits over the inturned lip4 and a lateral flange 8 which extends into and is retained -by thebracket 5. The side wall of the V-shaped end 7, which faces toward theweb 2, is provided with parallel sealing lips 9. The function of thesealing member d will be brought out more fully hereinafter.

Near the weatherside flange 3, the web 2 is interrupted by achannel-shaped mounting pad 10, extending internally from the webmember, and terminating in an inclined ramp surface 11 which slopestoward the roomside margin of the web 2, that is, away from theweatherside flange 3. The ramp surface 11 may include an extension whichprojects laterally fr-orn the mounting pad 1?. The margin of the rampsurface 11, nearest the weatherside flange 3, is provided with a stop12.

The roomside margin of the web 2 is provided with a roomside mountingpad 13 terminating in a ramp or inclined surf-ace 14, disposed at alesser height from the web 2 than the ramp sur-face 11. The ramp surface14 is also provided with a stop 15 corresponding to the stop 12. Whenthe mounting frame member 1 is formed into a rectangular framestructure, the opening defined by the outside mounting pad 10 is smallerthan the opening defined by the inside mounting pad 13.

The roomside mounting pad 13 is provided with a slot which is opentowards the roomside margin of the web 2. The confronting Walls of theslot are provided with screw/receiving serrations 16.

The rectangular, outer window frame structure, formed by the mountingframe member 1, is set into a window opening provided in a building wall17 and supported relative to the sides of the opening by suitable shimsor mounting blocks 18. Bolts 19 secure the outer frame structure inplace. In addition, grouting or other cementious material is placedbetween the roomside and Weatherside margins of the web 2 and thesurrounding walls of the window opening. At the weatherside margin ofthe web 2, a suitable sealant 21 is also applied.

The weatherside portion of the outer frame structure formed by themounting frame member 1 receives a Weatherside windowpane frame member22 formed into a rectangular frame substructure. The weathersidewindowpane frame member 22 includes a cross web 23 having a weathersideend 24 offset toward the mounting frame member 1. A weatherside-directedlip 25 overlies the offset Weatherside end 24 and an internally directedcatch lip 26 confronts the lip 25.

At the side of the oifset end 24 confronting the Web 2, there is formeda Weatherside facing channel 27 which conforms to the V-shaped end 7 ofthe sealing member 6, and is sealingly engaged by the sealing lips 9.

The web 23 of the weatherside windowpane frame member 22 is providedwith an external mounting channel 2S directed toward and in registrywith the weatherside mounting pad 1t). The mounting channel 28 receivesa mounting cushion 29, formed of rubber or other elastomer, and havinglateral sealing lips 39 which engage the side walls of the mountingchannel 28 and peripheral sealing lips 31, which seat on the inclinedramp surface 11 in a folded condition. Between the ramp 11 and themounting channel 2S, the cushion 29 is provided with lateral shouldersto limit entrance of the cushion into the channel.

Disposed internally of the cross web 23 is a weatherside windowpane stopflange 32 around which is wrapped a gasket strip 33, formed of rubber orother elastomer, and having an interlocking ange 34, the extremity ofwhich is received in a groove 35 provided in the stop ange 32. Theopposite margin of the gasket strip 33 overlies a portion of the web 23adjacent the stop flange 32.

A weatherside windowpane 36 is located at the weatherside of the stopflange 32, over the lip 25. lts margins yieldably bear against theinterlocking flange 34 of the gasket strip, Aand the windowpane ispositioned within the rectangular opening formed by the weathersidewindowpane frame member by means of mounting blocks 37, formed of rubberor other elastomer. The weatherside margin of the windowpane 36 receivesa sealant strip 3S,

lformed of rubber or other elastomer, and which may be lof the web 43 isoffset as indicated by 44, corresponding to the offset weatherside end24. Similarly, the offset end 44 is provided with an overhanging lip 45which confronts a catch lip 46 at the extreme roomside end. Adjacent theoffset end 44, the web 43 is provided with mounting channel 47,corresponding to the mounting channel 28, but of greater depth. Themounting channel 47 receives a second mounting cushion 29 which engagesthe roomside mounting pad 13.

The web 43 is provided at a side opposite from the mounting channel 47with a roomside windowpane stop flange 48 corresponding to theweatherside windowpane stop flange 32. The flange 48 is equipped with agasket strip 33 having an interlocking flange 34 wrapped over theextremity of the stop flange. A roomside windowpane 49 rests against theinterlocking flange 34 and is peripherally supported by mounting blocks37.

The roomside margin of the windowpane 49 is covered by a roomside Windowframing member 50 of channel shaped cross section corresponding to theweatherside window framing member 39. The framing member 50 is providedwith a laterally facing marginal channel 51 which interlocks with thelip 45 and a latching lip 52 which engages the catch lip of 46. Asealant strip 38 is interposed between the framing member 50 and theroomside windowpane 49. The surfaces of the two framing members 39 and5t) covered by the sealant strips 33 are preferably serrated orotherwise roughened to provide interengagement with the surface of thesealant strip.

The roomside margin of the web 43 is provided with a roomside coverplate or flange 53 which covers the mounting frame member 1 and overliesthe margin of the building Wall 17 surrounding the window opening. Theroomside cover plate 53 is provided at its margin remote from the web 43with a slot 54 directed away from the web 43. The slot 54 receives anoffset flange y55 formed of rubber or other elastomer, and attached to asealing tube 56 interposed between the marginal portion of the coverplate 53 and the wall 17.

The roomside face of the cover plate 53 is provided with a channel 57disposed in registry with the slotted edge of the mounting frame member1 having the screw-receiving serrations 16 therein. Screws or bolts SSextend through openings in the channel 57 .and screw thread between theserrations 16. The head of each bolt is provided with a grommet 59yformed of rubber or other elastomer. The channel 57 is covered by acover strip 60 having inturned flanges 61. Fitted between the inturnedflanges 61 are a plurality of retainer clips 62 of channel shaped crossseetion and including spring flanges 63 which engage internal ribs 64provided within the channel 57.

The cross webs 23 and 43 of the weatherside and roomside windowpaneframe members 22 and 42 are disposed in a common plane and terminate inconfronting relation to each other. The confronting margins of the Websare provided with flanges 65 which extend toward the mounting framemember 1 in parallel relation to each other. The extremities of theflanges 65 have outturned retainer lips 66. The confronting flanges 65are connected by a vibration isolating and sealing member 67 formed ofrubber or other elastomer. The isolating member is essentially W-shaped;that is, the isolating member includes a central flange 68 which litsbetween the confronting flanges 65 and side flanges 69 overlying theremo-te sides of the flanges 65. The outer surfaces of the side flanges69 are provided with sealing lips 7l). The isolating member 67 isadapted to lit within a retainer member 71 of channel-shaped crosssection. The side walls of the retainer member which lit over thesealing lips 7l) `are serrated to assure a sealing lconnection and alsoto secure the retainer member 71 on the isolating member 67.

The space between the gasket strips 33 which cover the windowpane stopflanges 32 and 4S receives an acoustical pan 72 having side flanges 73which bear yieldably against the gasket strips 33. The web of theacoustical pan between the flanges 73 is provided with slots 74 or isotherwise perforated in a suitable pattern. The space between theacoustical pan and the frame members 22 and 42 is filled with asound-absorbing material 75 and desiccant. The sound-absorbing materialmay be glass wool or fibrous material. The desiccant may be silica gel.

The window construction is installed as follows:

An outer frame structure is formed from four of the mounting framemembers 1 and is set in place within a window opening. The sealingmember 6 is fitte-d over the weatherside of flange 3. The remainingcomponents of the window construction are preassembled as a unit andthen slipped laterally within the outside frame structure. The mountingcushions 29 ride on the ramp surfaces 11 and 14. The weatherside facingchannel 27 engages the sealing member 6 and the bolts 58 are screwthreaded into the serrations 16 so as to draw the roomside cover plate53 and sealing tube 56 snugly against the roomside wall surface.

It will be noted that the weatherside windowpane carrying substructureis isolated from the roomside windowpane carrying substructure by reasonof the gasket strips 33 and isolating member 67. Both of thesesubstructures are isolated from the outer frame structures by themounting cushions 29. The weatherside windowpane substructure is alsoisolated fro-m the outer frame structure by the sealing member 6, and,correspondingly, the roomside Windowpane substructure is isolated fromthe wall by the sealing tube 56 and is isolated from the outer framestructure by the grommets 59 surrounding the head ends of the bolts 58.As a consequence the transmission of noise or vibration in eitherdirection through the window is materially reduced. i

It will also be noted that the various components of the windowconstruction may be rapidly disassembled; and inasmuch as the innerwindow frame structure comprising the two substructures, which carry theweatherside and roomside windowpanes, is installed as a unit, thisassembly may take place at a factory rather than at the point of use,and may be accomplished at a minimum of expense and time. Such factoryassembly also ensures a hermetically sealed compartment between the twowindowpanes.

Reference is now directed to FIGURE 5, which illustrates a modifiedformof the window construction adapted as a triple-pane window. Theconstruction is the same as that shown in the first described structure,except that the frame members 22 and 42 are separated to provide spacefor a center window frame member 76.

The center Window frame member 76 is channel-shaped and provided withflanges 77, similar to the confronting flanges 65 of the frame members22 and 42. The frame members 22, 76 and 42 are connected in series by apair of isolating members 67 held in the retaining channels 71.

The center window frame member 76 is provided with a fixed stop iiange78, corresponding to the flanges 32 and 48, and a removable stop flange79 secured to the frame member 76 by screws. The stop flanges deiine achannel which receives a window S0 which rests on the mounting blocks 37in the manner of the windowpanes 36 and 49. Gasket strips 33 center thepane between the iianges 7S and 79. In this construction two acousticalpans 81 are used which are similar to the acoustical pan 72 except thatthey have less width.

Reference is now directed to FIGURE 6. In this construction, the doublewindow arrangement shown in FIGURE l is utilized without change exceptthat the acoustical pan 72 is omitted, and, instead, two window framemembers 82 are provided. Each window frame member 82 includes achannel-shaped stop S3 from which extends a lateral shelf 84 terminatingin a latch bead 85.

Fitted over the shelf is a channel-shaped retainer member 86 having alatching means 87 which cooperates with the latch bead SS. The retainermember 86 includes a lateral lip 88 which extends toward the channelstop 83 and forms therewith an inwardly open channel having a cushion 89which receives a windowpane 96.

The two window frame assemblies are mounted between the gasket strips 33and the excess space is lled with separator strips 91, of rubber orother elastomer.

It will be noted that if only three panes are required, one of thecentral windowpane units may be omitted and -an acoustical pan ofappropriate width substituted.

While particular embodiments of this invention have been shown anddescribed, it is not intended to limit the same to the exact details ofthe constructions set forth, and it embraces such changes,modifications, and equivalents of the parts and their formation andarrangement as come within the purview of the appended claims.
